After finding that my home-made radio controls didn’t quite work, I added some capacitors this morning and it’s made a huge difference. Previously, whenever the motors turned, the receiver lost connection to the transmitter and it developed a “mind of its own”. I thought it might have something to do with the motors draining too much power and I was right, the capacitors have fixed the problem, almost. The capacitors I’ve used are just some that I had lying around. One is for a 20v circuit, the other for a 50v circuit, whereas the battery I’m using is only 9v. For the moment, the motors do as they are asked and turn in the right direction, they just don’t have much power. Hopefully when the new capacitors arrive I’ll have a fully working system. Fingers crossed…
